The sides of a scalene triangle are of ........... lengths.

Answer

To solve the question about the sides of a scalene triangle, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Triangle**:
- A triangle is a polygon with three edges and three vertices.
- There are different types of triangles based on the lengths of their sides.

2. **Identifying the Type of Triangle**:
- A scalene triangle is a type of triangle where all three sides have different lengths.

3. **Defining the Sides**:
- Let’s denote the sides of the scalene triangle as \( a \), \( b \), and \( c \).
- In a scalene triangle, the following conditions hold true:
- \( a \neq b \)
- \( b \neq c \)
- \( c \neq a \)

4. **Conclusion**:
- Therefore, the sides of a scalene triangle are of **different lengths**.

### Final Answer:
The sides of a scalene triangle are of **different lengths**.
